What is the history of PVI? My impression is that in the early days, the ablation was done inside PV. The downside was that it could cause stenosis, restricting blood flow. The lesion site was moved proximal, which reduced stenosis. Now the lesion is essentially on the atrial wall. Is that correct? Any details or correct terminology?

That is correct.

there are cardiac ANS clusters in the antrum as well, and that part of the effectiveness of the isolation the PV at the antrum is the inescapable/fortuitous killing off of those autonomic clusters.

Thanks. Do you have an idea of the cause and mechanism of yours?Quote

I was under the impression that thermal ablation does not discriminate, all cell types within the thermal zone die. And there appear to be clusters of ICNS neurons in the PV antrum, a frequent ablation zone for isolating PVs

while autonomic function may change <snip> it seems to be a modification rather than zapping the complete autonomic ganglia.
